Ignored SMART errors keep coming back

[Dave-847]

I have  numerous hard drives that have an LCC count higher than the moon, but no issues with the drives.

The 2TB WD Green drives (WD20EARX and WD20EZRX) were put into my server first.

Using WDIDLE3 I got the head parking issue under control and I ignored the Load Cycle Count SMART warning.

That's been weeks ago and everything's worked fine.

I recently put my Segate 4TB (ST4000DM001) into my pool and found I had a similar LCC issue.

I got the drives to stop parking the heads and ignored the SMART warnings for those drives as well.

 

It seems randomly, (although it may be tied to a reboot) the SMART warnings reoccur, but just for the Seagate drives.

The WD drives do not regenerate the SMART error.

Any ideas why this might be?

This should depend on how you ignored the warning.

 

When you ignore it, there should be two options: 

• Ignore current value
• Permanently ignore.

The first will warn you again if the value increases (sounds like what is going on). The second will prevent that value (or values) from notifying you ever again. 

 

If you did the wrong one, you can open the SMART details window, un-ignore and then re-ignore and select the option you want.

I was using the "Ignore current value".

The way I read the alternate option was that it would permanently ignore all SMART errors on the drive.

Can you confirm that is NOT the case?

I can permanently ignore just the LCC count but any other SMART errors will still flag me?

 

It turns out that the Seagate count increases by 1 each time the server is shutdown.

The WD drives evidently don't do that.

 

Thanks for your help.

Specifically, it only ignores the current values that are causing the warnings to appear.  

So if the Load Cycle Count is the only SMART value that is triggering a warning, using the "Permanently Ignore" option will ignore any warning triggered by the Load Cycle Count (eg, the LCC value increasing).
